FIRING MECHANISM.

Specification of Letters Patent.

Application filed January 9,1918. Serial No. 741,124.

To all whom it may concern:

Be it'known that we, HENRY F. RoJoHN and WILLIAM DICK, citizens of theUnited States of America, residing at Greenock, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Firing Mechanism, of which the following is aspecification, reference being had therein to. the accompanying drawing.

This invention relates to a firing mechanism for a trlggerless gun, andmore particularly to a mechanism that can be advantageously used inconnection with a repeater or what is commonly known 'as a pump gun, oras a matter of fact, in connection with any gun that has a concealedhammer.

The primary object of our invention is the provision of positive andreliable means,

as will be hereinafter set forth, for locking a firing mechanism againstaccidental action, thereby. preventing accidental discharge of a gun,until such time that the user of the gun positively sets the firingmechanism for action.

Another object of our invention is to provide a safety device for firingarms consisting of comparatively few parts that can be easily assembledand concealed within the stock of gun for locking the gun againstaction.

' further object of our invention is to provide a simple, inexpensiveand durable safety device for repeater firing arms that does not impairthe appearance of a fire arm or materially increase the. weight thereof.

With the above and other objects in view the invention re ides in thenovel construction, combination and arrangement of parts to behereinafter specifically described and then claimed.

Reference will now be had to the drawing,

' wherein Figure 1 is a side elevation of a firing mechanism showing themechanism in a tired position and said mechanism relatively to the stockof a repeater gun, Fig. 2 is a similar view showing the firing mechanismcooked, and Fig. 3' is a cross sectional view of a portion of a stock ofa gun showing the firing button.

I Further describing our invention in detail with reference to theaccompanying drawing, wherein like numerals denote corresponding partsthroughout: 1 denotes a. portion of a conventional form of repeater gunthat has a hammer 2 pivoted within the gun for striking a firing pin 3,,said hammer being cocked when the mechanism of the gun is actuated toeject a shell and place another cartridge in position for firing. Thepivoted end of the hammer '2 has a shoulder 4. and pivetally connectedto the same end of said hammer, as at 5 is a spring actuated plunger 6.The plunger 6 extends lever is adapted to engage the shoulder d of thehammef 2 and hold the hammer cooked or set, as shown in Fig. 2. Therelease lever is held in engagement with the shoulder 4: by the combinedtension of the spring 9 and a leaf spring 12, carried by the stock ofthe gun and engaging the under side of the release lever- The inner endof the release lever 10 is engaged by a double conical-shaped springheld shiftable member 13 arranged transversely of the stock of the gun.The member 13 has shanks 14 extendin through ofl'set walls 15 of thestock of the gun and said shanks have firing buttons 16 housed in therecesses 17 formed by the ofiset walls 15. Encircling the shanks 14,between the ends of the member 13 and the Walls 15 are coiledcompression springs 19. The tension of the springs 19 is sufficient tohold the member 13 where- 'by the release lever 10 will be intermediatethe ends thereof. In other words, the release lever will normally engagethat portion of' the member 13 of sniall diameter. By pressing inwardlyupon either of the firing buttons 16 the release lever is shifted andthe hammer 2 released. With a firing button at each side of the stock ofthe gun,

the gun can be used by right-handed or lefthanded persons. A

Located within the stock of the gun,

adjacent to the inner end of the release lever, is a Z-shaped lockingarm 20 that is g ided by the stock of the gun. The outer Patented May20,1913.

end of the arm 20 has a button 21 to permit of the arm being easilyshifted, and the inner end of the arm is adapted to' extend over theinner end of the lever 10. Withthe arm 20 in one position, as shown inFig. 2, the lever 10 cannot be moved by the member 13, and with the arm20 in the position shown in Fig. 1, the gun can be fired by pressingeither one of the buttons 16.

It is thought that the utility of our invention will be apparent withoutfurther description, and while in the drawing there is illustrated apreferred embodiment of our invention, we would have it understood thatthe structural elements are susceptible to such modifications andvariations as fall within the scope of the appended claims. What weclaim is 2-- 1. In a firing mechanism for guns, a spring actuatedhammer, a release lever for holding said hammer cocked, a doubleconical-shaped spring pressed shiftable member normally engaging saidlever for moving said lever to release said hammer and means wherebysaid member can be shifted through one side or the other,. and

an arm movable above said release lever for locking said lever againstmovement when said hammer is cooked.

2. In a firing mechanism for guns, a spring actuated hammer, a releaselever for holding said hammer cocked," a double conical-shaped springheld shiftable member normally engaging said release lever,

means to. facilitate shifting said member and w means whereby saidmember can be shifted through one side or the other, and means locatedabove said lever for lockin said leveraga'inst movement when said ammeris cocked.

3. In a firing mechanism for guns, a spring actuated hammer, a releaselever for holding said hammer cocked, a double conical-shaped springheld shiftable member normally engaging said release lever, and means tofacilitate shifting said member from either one side or the other.

4. In a firing mechanism for guns, the combination with a gun stock, anda spring actuated hammer, of a pivoted release lever arranged in thestock of said gun for holding said hammer cocked, a double conicalshapedmember supported by offset portions of the walls of said stock andnormally engaging said release lever whereby said lever can be moved outof engagement with said hammer by shifting said member and means wherebysaid member can be shifted from either one side or the other, and meansWithin the stock of said gun for restoring said member to its normalposition after each actuation thereof.

In testimony whereof we aflix our signatures in the presence of twoWitnesses.

HENRY F. ROJOHN. WILLIAM DICK.
